Vibram’s FiveFingers look like something Spider-Man would wear, especially if you look at them from the bottom. Which is a good thing; I love Spider-Man. But I doubt that’s what they were going for when they designed them.

In a way they’re kind of the anti-shoe. Which is part of their marketing. “Go barefoot without being exposed”, they invite. Their sure-footed grip sole will act like “a second skin to offer a gecko-like grip over a variety of terrain.” And from the looks of them, it seems to be true. From what I can tell, the shoes guard your feet from rocks, sharp objects and other debris while giving you that freestyle barefoot feeling.

And according to their site, the shoes promote “a natural walking motion, reducing impact on your knees, hips, and lower back.”

Here’s how they work: the specially designed sole “follows the contours and flex points of your feet” while the five fingers (or rather, toes) go in individual slots that give you a more balanced, natural movement. (Which kinda makes sense, considering that’s what toes are for. It’s like winter handwear — why put on restricting mittens when you can wear gloves that allow you to use your fingers?) Meanwhile, the Razor-siped sole protects your feet from hot pavement, sand or rocks while gripping the ground to protect you from slips.

Plus, an adjustable gizmo in the back allows you to create a personalized fit that matches your foot.

I’m guessing they take a little getting used to, but I like the idea. Plus they’re made from non-animal products, which is even better.
